One simple rule -

One simple rule to follow when in doubt is to always apply the thinnest products first. This means you should apply your liquid and water-based products first, working up to your thickest products such as rich creams and oils.

The texture of the product -

With this simple rule, you will understand that thinner formulas won’t penetrate through thicker textures (and nothing will penetrate through an oil).

AM vs PM routines -

It's also important to understand that you need two different skincare routines, one for the morning and one for the evening. There will be slight changes in the products used for AM and PM.

Morning routine -

Morning routines are about prevention and protection. Your face is going to be exposed to environmental aggressors, so necessary steps include moisturizer and sunscreen.

Cleansing -

First things first, you will need either a water- or oil-based cleanser for when you wake up. This step is important because the cleanser will remove grime and residue that built up overnight.

Eye cream -

Apply first eye cream after cleansing in the morning. These contain potent blends of active ingredients that are worth getting onto bare skin.

Serum -

Next comes serum. These have a lower molecular weight than creams and contain serious ingredients that need to penetrate the skin to really get to work.

Be attentive -

Pay attention to what's in your serums, as certain ingredients boost each other’s efficacy. For example, vitamin E and ferulic acid enhance the effects of other vitamins, while vitamins C and E correct dark spots better when under sunscreen.

Don't forget SPF -

Finally, apply your daytime moisturizer and your SPF. Let your SPF sink in completely for about seven minutes before applying makeup.

Make sure you get enough SPF -

Even though lots of multi-functional day creams are also SPF hybrids, you will need at least 1/2 a teaspoon of product to get the right amount of sun protection.

Spot treatment -

Spot treatments can be tricky, as some don't play well under makeup or dry well. For these reasons, it might be better to reserve your spot treatment for your evening routine.

Night routine -

The night routine is about repairing the damage done during the day with thicker products. This is also the time to use anything that makes skin sensitive to sunlight, including physical exfoliants and chemical peels.

Cleansing -

Start off by removing your makeup with a makeup remover. Then, just like in the morning, use a cleanser to get rid of any lingering dirt.

Exfoliate -

Exfoliation removes dead skin cells from the surface of your skin. Some chemical exfoliators can also remove impurities from deeper within your skin and prevent breakouts. But skip this step if your skin is already irritated.

Clay mask -

Clay masks work to unclog pores and can also absorb excess oil. They are best applied at night to remove leftover dirt, and help the skin soak up other products.

Under-eye patches -

Under-eye patches are great for tired eyes and are designed to relieve puffiness and aid in surface hydration. They also help diminish the look of thin lines.

Toner -

Toners can help remove leftover residue from other steps in your routine and balance your skin’s pH. Apply the product to a cotton pad and swipe over your skin.

Hydrating mist -

Hydrating mists are excellent for giving the skin a moisture boost. Make sure to use one with humectant ingredients like lactic acid, hyaluronic acid, and glycerin.

Acid treatment -

Acids can help reduce signs of aging, scarring, acne, plus they can help even out your skin tone. For beginners, try out glycolic acid. Other options include acne-busting salicylic acid and moisturizing hyaluronic acid. This will give you a brighter and more even complexion.

Serum -

Just like in the mornings, serums should also be applied in the evenings. Choose one that benefits your skin needs, whether it’s pro-aging support, moisturizing, brightening, or spot reduction.

Spot treatment -

Anti-inflammatory products are for blemishes with a head. Before applying, make sure your skin is clean. Use a small amount of product and leave to dry.

Hydrating serum or mask -

With the ability to pack a lot of moisture, hydrating serums and masks are wonderful for dry skin. Try refrigerating the product before using it and enjoy some additional anti-inflammatory benefits.

Eye cream -

A richer nighttime eye cream can help improve issues like tiredness and fine lines. Look for a high concentration of peptides and antioxidants.

Face oils -

A face oil is great for dry or dehydrated skin. The evening is the best time to apply thicker oils that may result in an unwanted shiny complexion.

© Shutterstock

Night cream -

While day creams are designed to protect the skin, these rich night moisturizers help with cell repair. A tip is to warm a small amount of product in your hands before distributing it evenly across your face.

Sleep mask -

If you don't want to use a night cream, try out a sleep mask. They help seal in all your other products and contain hydrating ingredients that are kept on overnight.

© Shutterstock

What to do if you have dry skin -

For dry skin, focus on hydration and building a healthy skin barrier. Swap out products that may be too harsh or acidic for those that add moisture and help retain it.

© Shutterstock

Careful with layers -

Sometimes if you apply too quickly or use too many layers of products, you'll notice pilling on the skin and the products will feel like they are rolling off. So remember to give your products enough time to absorb into the skin and dry between steps.

The bottom line -

The most important thing is finding a skincare routine that works for you and that you’ll follow. Don't feel pressured to include every step mentioned.
